Interesting topic mark. I made an assumption a while ago that the 1.2 cams would be less agressive due to the fact that the 1.2 makes its peak power 400 rpm less than the 1.0. However looking at those cam measurments there the 1.2 have a higher lift, but this on its own does not help since we need to know the duration which is quite hard to get hold of. I can say this however I have tried a 1.0 head on a 1.2 engine (1.0 head is higher compression) the result was not really worth the hassle. Its unclear really weather it made any difference or not.
